Title: Digital servo equipment
Inventor: TABUCHI JUNICHIRO
IPC: H02P29/00
Filed: 1989-03-08
Abstract: PURPOSE:To widen the lead-in range of an apparatus by making the amplitude of a phase error signal larger than that of a speed error signal, by dividing said phase error signal into 1/n, and thereafter by combining sid phase error signal with said speed error signal. CONSTITUTION:An inputted FG signal is divided in half by software to generate a speed error signal, and further divided in half to generate a phase error signal. Then, said phase error signal and speed error signal are combined to output the control signal of a cylinder motor. That is, said control signal is generated so that the amplitude of said phase error signal becomes larger. Also, conversion gains {the ratio of the change of an error signal level to the change of a phase difference (time difference)} at the time of generating both error signals are the same, i.e., the lead-in range of an apparatus can be set widely.

Title: Method of pattern formation and manufacture of semiconductor device
Inventor: NIINOBU HIROHARU
IPC: H01L21/66
Filed: 1990-03-07
Abstract: PURPOSE:To enable formation of an accurate pattern within an allowable error even if a warp amount of each substrate is not constant by correcting a pattern position on a mask, considering an allowable limit value for warp of a substrate. CONSTITUTION:When a warp equivalent to an allowable maximum value is generated in a substrate 10, an interval between rear edges T2, E2 is made equal to a margin  Y. As for a warp of an allowable maximum value or less, an interval between rear edges T2, E2 is necessarily made larger than a margin  Y. Meanwhile, the smaller a warp of the substrate 10 is, the narrower an interval between front edges T1, E1 is. Therefore, when a warp equivalent to an estimated minimum value is generated in the substrate 10, an interval between front edges T1, E1 is made coincide with a margin  X and it is possible to effectively prevent a front edge E1 of an electrode 5a from protruding over a front edge T1 an n-emitter region 14a to a warp of an estimated minimum value or less.
